To all whom it may concern Be it known that I, Fnnnnron WV. B'reons, acitizen of the United States, residing at Virginia, in the county'o-fSaint Louis and State of M innesota, have invented a new vide 'a novelmeans whereby a rivet may be held, i rran inaccessible place, while. therivet is being butt-ended.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the abovearnd other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the detailsof construction hereinafterdescribed and claimed, it being understood that,"

in the precise embodiment of the invention shown can be made withoutdeparting from the spirit ofthe invention.

In the accompanying drawings:'-

Fig. 2 is a fragmental 22 of Fig. 1;

In the accompanying drawings, the numerals 1 and 2 denote the endmembers of a boiler provided with tubular flanges 3. The end members 1and 2 are supplied with openings 5 adapted to receive stay bolts 6. Letit be assumed that it is desired to con nect the tubular flanges 3 bymeans of rivets 7 and that it will be somewhat difficult, in the absenceof the device hereinafter desection onthe line specific-anon of LettersPatent.

scribed, hold the inner ends of the rivets 7 while the outer endsthereof are being butt-ended. The device forming the subject matter ofthis application. has been shown, by way' of illustration, as being usedin connection with a portion of a boiler, but i it is of course to beunderstood that the structure is capable of many uses, other than theone specified.

-In carrying out the present invention there is provided a lever 8supplied at one end with a broadened hea 9, the other end,

justment in any of theopenings 15-, the pivotmemberbeing' mounted in anyselected pair of the openings 5 of the members 1 and 2. In this way, thelever :8 will be fulcrumed on the members 1 and 2 for swinging movementtransversely of the tubular flanges 3* which form the fire door hole 4.V

The invention includes a fulcrum bolt 18 comprising ahead '19 and ashank 20. The head 19 of the fulcrum bolt 18 has any (lee sired numberof openings 21. The head 19 of the fulcrum bolt may be placed the recess14 of the lever 8 and the pivot member 17 may be mounted for adjustment,in either of the openings 21 in the head 19 of the fulcrum bolt. Theshank 20 of the fulcrum bolt 18 may be inserted through alined rivetholes 22 in the boiler parts 12, as shown in Fig. 3, a nut 23 beingthreaded on the inner end of the shank 20. Thus, the lever 8 isfulcrinned in a manner which differs slightly from that shown in Fig. 1.

One end of a flexible element 24 is mounted in the hole 16 of the leverand extends laterally, between the end members 1 and 2, to a point atone side of the boiler. If desired, the flexible element 24 may be eX-tended outwardly through one of the openings 5 in the part 1. Y

The outer end of the flexible element 24 may be mounted on a hook 25constituting a part of a chain 26 connected with a finger 27 tighteningdevice may be of ing fulcrumed on a cleat 29 mounted on the floor. Thelever 28 and attendant parts constitute a tightening device, and thisany desired form adapted toput the flexible element 24 under tension, 7

When thelever 8 is fulcrumed as shown in Fig.1 or is fulcrumedon thebolt 18, as shown in Fig. .3, the head of a rivet is engaged with theanvil 11 of lever, between the wings 12. WVhen tension is exerted on theflexible element 241, the lever will be held in place, so as to retainthe rivet, and the,

rivet may be butbendedreadily; Since the head 9 of the lever is providedwith a plurality'of openings 15, and since-there are severalopenings 21in the head 19 of the 7 fulcrum bolt 18, it will be obvious that manyvided intermediate its ends with an anvil for. the rivet; means forsecuring and ful: cruming one end 'of the lever pivotally butdetachablyupon the structure wherein the rivet is to be inserted; and means forapplying tension to the other end of thelever.

" comprising a lever provided intermediate its ends with an anvil forthe rivet and curved to extend part way a'round the tube; mechanism forfulcrumlng the lever at one end; and means for operating the lever fromthe other end thereof, said means and said mechanism being spaced toadmit the tube therebetween. v 1

3. In a devicefor holding rivets, a lever provided at one end with arecess and hava tightening device assembled with the other end of thelever. r 7

4. In a device for. holding rivets, a lever provided at one end with arecess and having a plurality of transverse openings com-T1 municatingwith the recess, the lever being provided. intermediate. its ends with.an an-,

vil; a pivot member adapted to be mounted in any of the openings,andextended across the recess; a fulcrum element having one of its endsdisposed in the recess, saidend of the fulcrum element having-aplurality of openings, in any one of 'which the pivot' member may bemounted; and a tightening device assembled with the other end of thelever. '7 1 l V 5. In a device for holding rivets, a lever 7 providedintermediate its end with an anvil and having projecting wings locatedon each side of the anvil, there being a recess in one end of the leverand saidend ,ofthe lever being supplied with a plurality ofopenings"communicating with the recess; a pivot member adapted tobe mounted inany of the openings, and extended across the recess;

a fulcrum element havingone of its ends 2. A device for holding a rivet1n a tube disposed in the recess,.said end ofthe fulcrum elementhaving-a plurality of openings, in any one of which the pivot member sbe mounted; and a tightening device assembledwith the other end of thelever.

In testimony that I claim the foregoing as Copies of this patent may beobtainedfor five cents each, by addressing the Commissioner of Patents,
